Improvement: switcg some gpio when transmitting on certain bands

[hubertmeier]

It would be very helpfull if we could switch gpio's when transmitting so we could switch different outputs for different low pass filters !

the gpio must be part of the command line:

example:

sudo /home/pi/WsprryPi/wspr --repeat --self-calibration XYZ12 XN39 10 10m 15m 80m --gpio 2 3 5

at start, all gio which are part of the command line must be defined as output, at 10m gpio 2 must be switched to H, all others L and so on ...

Thank you

Hello, I also thought about this feature. It would be cool to have a standard 4-bit output for switching bands
